I'm rocking the 3" ATP Turbo adapter. You'll be providing couplers that accomplish the same thing.

This is the cold side of my charge pipes (notice lowport intake). This is an extremely rare way to run the charge pipes (maybe even a first?) and I'm extremely happy with the way it turned out. Actually, I've been sort of keeping this under wraps. I tend to think this method will catch on once I post it, but whatever. I'm posting this so you have an idea of the height that I had to deal with. I had to have my intake pipe go
under this charge pipe yet managed to get it over the relay box you see in the picture.

This shows the radiator hose I was talking about very well. Right now it's in the stock location (I think). You can see how it's meant to avoid the radiator fan. If you flip it around, you open up possibilities.

And the pipe on the right is what I had to make. As you could see already, I don't have a battery to contend with. This places the air filter at the battery location basically. You should be able to place the filter behind it, or somewhere else using typical bends without issue I feel. The longer straight section mounts to the turbo side. The filter attaches immediately after the second 90 degree bend.
